Definitions

  • the present invention relates to reconstituted high density lipoprotein formulations, and in particular to formulations with suitable stability and biological properties for pharmaceutical use.
  • High-density lipoproteins form a range of lipoprotein particles found in normal serum.
  • Mature HDL particles are present in the form of a globular structure containing proteins and lipids. Within the outer layer of these particles are the more polar lipids, phospholipids and free cholesterol, all having charged groups orientated outwards, towards the aqueous environment. The more hydrophobic lipids, such as esterified cholesterol and triglycerides, reside in the core of the particle. Newly formed or nascent HDL particles lack the lipid and are discoidal in shape. Protein components are embedded in the outer layer.
  • the main protein component is apolipoprotein A-I (Apo A-I) with smaller amounts of Apo A-II, Apo A-IV, Apo CIII, Apo D, Apo E and Apo J.
  • Various other proteins reside on the HDL particle, such as lecithin-cholesterol acetyl transferase, PAF acetylhydrolase and paraoxonase.
  • rHDL reconstituted HDL
  • the artificial particles contain components of the natural particles, in particular Apo A-I and lipids.
  • rHDL reconstituted HDL
  • lipids e.g. 1,2-dipalmitoyl- sn -glycero-3-[phospho- rac -(I-glycerol)] (DPPG)).
  • rHDL formulations It is convenient for rHDL formulations to be lyophilized (freeze-dried) before use. Lyophilization is a commonly used method for preparing solid protein pharmaceuticals. However, this process generates a variety of freezing and drying stresses, such as concentration of the solubilized protein, formation of ice crystals, pH changes, etc. All of these stresses can denature proteins to various degrees. Thus, stabilizers are often required in a protein formulation to protect protein stability both during freezing and drying processes. In order to maintain the stability of rHDL formulations during lyophilization, stabilizers like sugars and sugar alcohols have been used.
  • US 5,089,602 discloses plasma-derived lipoproteins that are stabilized with 10% sucrose or a mixture of 10% sucrose and 5% mannitol.
  • WO 2012/000048 discloses sugar and sugar alcohol stabilizers used at a concentration from about 65 to 85 g/L of rHDL formulation (equivalent to about 6.5 to 8.5% w/w).
  • WO 2012/109162 discloses sucrose and mannitol as stabilizers, used in a mixture at 4% w/w and 2% w/w respectively.
  • An investigation into the manufacturing and shelf stability of rHDL was carried out in Kim et al, Biotechnology and Bioprocess Engineering 16, 785-792 (2011 ).
  • rHDL with an Apo A-I:soybean PC ratio of 1:150 could not be sufficiently stabilized with 1 or 5% sucrose, whereas 10% sucrose was described as optimal.
  • rHDL formulations of these documents are intended for infusion therapy, but high sugar concentrations in infusion products may cause or exacerbate renal problems. This is a particular problem in the target patient population for rHDL, because these patients are often renally impaired.
  • an object of the present invention was to provide alternative or improved rHDL formulations compared to these previous formulations.
  • the inventors sought stable rHDL formulations with reduced renal toxicity.
  • the rHDL formulation of claim 1 shows good long-term stability. By containing less lyophilization stabilizer than previous formulations, the formulation also presents less risk of renal toxicity.
  • the low lyophilization stabilizer concentration may also allow the rHDL to perform better in functional assays of rHDL function.
  • amino acids, particularly proline are useful lyophilization stabilizers for rHDL formulations.
  • the invention provides an rHDL formulation comprising an apolipoprotein, a lipid and a lyophilization stabilizer, wherein the ratio between the apolipoprotein and the lipid is from about 1:20 to about 1:120 (mol:mol).
  • the lyophilization stabilizer is present in a concentration from about 1.0% to about 6.0% (w/w of rHDL formulation), e.g. from 1.0, 1.1, 1.2 or 1.3 to 5.5, 5.6, 5.7, 5.8, 5.9, or 6.0.
  • This low amount of lyophilization stabilizer may reduce the risk of renal toxicity. It is also particularly suitable for patients receiving contrast agents during acute coronary syndrome therapy (ACS), since these agents may compete with lyophilization stabilizer for clearance in the kidneys.
  • the lyophilization stabilizer is present in a concentration from about 1.0% to less than 6.0% e.g. from about 1.0% to 5.9%.
  • the lyophilization stabilizer is present in a concentration from about 3.0% to less than 6.0%, e.g. from about 3.0% to 5.9%. More preferably, the lyophilization stabilizer is present in a concentration from about 4.0% to 5.5%, particularly 4.3% to 5.3%, more particularly 4.3% to 5.0%, and most preferably 4.6% to 4.8% (w/w).
  • Such formulations show good stability and low renal toxicity.
  • the ratio between the apolipoprotein and the lyophilization stabilizer is from about 1:1 to about 1:3 (w:w).
  • the ratio between the apolipoprotein and the lyophilization stabilizer is from about 1:1 to about 1:2.4 (w:w), e.g. less than 1:2 (w:w).
  • the ratio between the apolipoprotein and the lyophilization stabilizer may be less than this, e.g. from about 1:1 to about 1:7, and in particular from about 1:1 to about 1:5 (w:w).
  • the invention also provides an rHDL formulation comprising an apolipoprotein, a lipid and a lyophilization stabilizer, wherein the lyophilization stabilizer comprises an amino acid.
  • the amino acid is proline.
  • the inventors have found that amino acids are good lyophilization stabilizers for rHDL formulations, particularly when in a mixture with low amounts of other stabilizers.
  • the invention also provides the aforementioned rHDL formulation for preventing or treating a disease, disorder or condition in a human.
  • the disease, disorder or condition is responsive to prophylactic or therapeutic administration of the rHDL formulation.
  • reconstituted HDL (rHDL) formulation means any artificially-produced lipoprotein formulation or composition that is functionally similar to, analogous to, corresponds to, or mimics, high density lipoprotein (HDL), typically present in blood plasma.
  • rHDL formulations include within their scope “HDL mimetics” and “synthetic HDL particles”.
  • lyophilization stabilizer means a substance that stabilizes protein during lyophilization. Such lyophilization stabilizers are well known in the art and are reviewed in, for example, Wang (2000) International Journal of Pharmaceuticals 203:1-60 .
  • a preferred lyophilization stabilizer for use in the invention comprises a sugar, a sugar alcohol, an amino acid, or a mixture thereof.
  • disaccharides such as sucrose are particularly suitable sugars for use as the lyophilization stabilizer.
  • Other disaccharides that may be used include fructose, trehalose, maltose and lactose.
  • trisaccharides like raffinose and maltotriose may be used.
  • Larger oligosaccharides may also be suitable, e.g. maltopentaose, maltohexaose and maltoheptaose.
  • monosaccharides like glucose, mannose and galactose may be used. These mono-, di-, tri- and larger oligo-saccharides may be used either alone or in combination with each other.
  • lyophilization stabilizers that are sugar alcohols may also be used. These sugar alcohols may also be used either alone or in combination.
  • a particular sugar alcohol for use in the invention is mannitol.
  • sugar alcohols that may be used include inositol, xylitol, galactitol, and sorbitol.
  • Other polyols like glycerol may also be suitable.
  • Amino acids that may be used as lyophilization stabilizers include proline, glycine, serine, alanine, and lysine. Modified amino acids may also be used, for example 4-hydroxyproline, L-serine, sodium glutamate, sarcosine, and ⁇ -aminobutyric acid. The inventors have found that proline is a particularly suitable amino acid for use as a lyophilization stabilizer.
  • the lyophilization stabilizer comprises a mixture of a sugar and a sugar alcohol.
  • a mixture of sucrose and mannitol may be used.
  • the sugar and the sugar alcohol may be mixed in any suitable ratio, e.g. from about 1:1 (w:w) to about 3:1 (w:w), and in particular about 2:1 (w:w).
  • Ratios less than 2:1 are particularly envisaged, e.g. less than 3:2.
  • the ratio is greater than 1:5, e.g. greater than 1:2 (w:w).
  • the formulation comprises less than 4% sucrose and 2% mannitol (w/w of rHDL formulation), for example 3% sucrose and 2% mannitol.

  • the lyophilization stabilizer comprises a mixture of a sugar and an amino acid.
  • a mixture of sucrose and proline may be used.
  • the sugar and the amino acid may be mixed in any suitable ratio, e.g. from about 1:1 to about 3:1 (w:w), and in particular about 2:1 (w:w). Ratios less than 2:1 are particularly envisaged, e.g. less than 3:2 (w:w). Typically, the ratio is greater than 1:5, e.g. greater than 1:2 (w:w).
  • the amino acid is present in a concentration of from about 1.0 to about 2.5% e.g.
  • the formulation comprises 1.0% sucrose and 2.2% proline, or 3.0% sucrose and 1.5% proline, or 4% sucrose and 1.2% proline.

  • sodium cholate (New Zealand Pharmaceuticals) was dissolved in buffer (10 mM NaCl, 1 mM EDTA, 10 mM TRIS, pH 8.0) and stirred until clear. Soybean phosphatidylcholine (Phospholipid GmbH) was added to an appropriate volume of the cholate and stirred for 16 h at room temperature.
  • the Apo A-I solution was diluted to a protein concentration of 9.0 mg/mL (determined by OD280) with 10 mM NaCl and mixed with an appropriate volume of the lipid solution to obtain protein to lipid ratio in the range of 1:45 to 1:65. The mixture was stirred at 2-8 °C for 30 min to 16 h.
  • the HDL mimetics were prepared by cholate dialysis using 1% sucrose as a diafiltration buffer. The eluate was concentrated to a protein concentration of 33 to 38 g protein /L. Sucrose was added to obtain the desired concentration (1%, 2%, 3%, 4%, 5%, 6.5%, 7%, 10% w/w). The pH of the solution was adjusted, with 0.2 M NaOH to pH 7.50 ⁇ 0.1 after which WFI (water for injection) was added to obtain a protein concentration of 30 mg/mL. The final formulations were then sterile filtered through a 0.2 + 0.1 ⁇ m filter and filled into 100 mL glass vials at 1.7 g protein per vial and lyophilized.
  • proline was added to the desired concentration. Proline maintains an isotonic formulation.
  • HPLC-SEC Size exclusion chromatography
  • Figure 1 shows a complete chromatogram of (1) internal control, 2: 5% w/w sucrose, 3: 6.5% w/w sucrose, 4: 7.5% w/w sucrose and 5: 10% w/w sucrose.
  • Figures 2B and 2C show the results for sucrose concentrations 1, 2, 3, and 4% (w/w) and formulations comprising sucrose and proline.
  • HDL particles are capable of sequestering cholesterol from plaques formed along artery walls or cells by interaction with the ATP-binding cassette transporter A1 (ABCA1).
  • ABCA1 ATP-binding cassette transporter A1
  • LCAT Lecithin-cholesterol acyltransferase
  • a plasma enzyme converts the free cholesterol into cholesteryl ester (a more hydrophobic form of cholesterol), which is then sequestered into the core of the HDL particle before being transported to the liver to be metabolized. If the sucrose content in the final formulation affected the efficacy of the rHDL particle, LCAT activity would decrease.
  • LCAT lecithin-cholesterol acyltransferase
  • the cholesterol and cholesteryl ester is extraction by liquid extraction with n-hexane.
  • the cholesteryl ester was separated from unesterified cholesterol using a solid phase extraction column (SampliQ Amino, Agilent) and measured by scintillation counting.
  • the count rate of the sample stored at 4 °C is subtracted from the count rate of the sample stored at 37 °C.
  • the same procedure is also performed with a reference sample.
  • the LCAT activity is expressed as % of the Reference sample.
  • Figures 3A and 3B show LCAT activity for 4-10% w/w sucrose formulations.
  • Figure 3C shows LCAT activity for 1-4% w/w sucrose formulations. Very little difference is seen in LCAT activity when the sucrose ranges from 5-10% w/w in the final formulation ( Figure 3A ), however a slight decreasing trend is evident when the sucrose is further reduced to 4% w/w ( Figure 3B ).
  • Figure 3D shows LCAT activity for formulations comprising sucrose and proline. No apparent trend in LCAT activity is observed for formulations containing sucrose and proline. Thus the efficacy of the HDL particle in sucrose/proline formulations is maintained.
  • Reverse cholesterol transport is a pathway by which accumulated cholesterol is transported from the vessel wall to the liver for excretion.
  • Cells efflux free cholesterol to lipid-poor Apo A-I via the ABCA1 pathway.
  • the cholesterol efflux assay measures the capacity of HDL to accept cholesterol released from cells. It is anticipated that if sucrose content affected particle formation and/or integrity, differences would affect cholesterol efflux.
  • RAW264.7 cells were obtained from the American Type Culture Collection (ATCC). Cells were cultured in DMEM (Dulbecco's modified Eagle's medium, Gibco) supplemented with 10% (v/v) foetal calf serum (FCS, Gibco), 2 mM glutamine, 100 units/mL penicillin and 100 ⁇ g/mL streptomycin in a humidified CO 2 incubator at 37 °C.
  • ATCC American Type Culture Collection
  • cells were seeded into 24-well plates at a density of 0.35 x 10 6 cells per well. The following day, cells were labeled with [1,2- 3 H]cholesterol (1 ⁇ Ci/mL, GE) in DMEM supplemented with 5% (v/v) FCS.
  • Radioactivity in cell supernatants was measured by liquid scintillation counting.
  • Total cell-associated [ 3 H]cholesterol was determined after extraction of cells in control wells for at least 30 minutes with 0.1 M Triton X-100. Cholesterol efflux was expressed as the percentage of the radioactivity released from cells into the medium relative to the total radioactivity in cells and medium. The difference in efflux between control and 8Br-cAMP-stimulated cells was taken as a measure of ABCA1-dependent efflux.
  • Figures 4A and 4B show that as sucrose concentration decreases from 7.5% w/w to 4% w/w the cholesterol efflux increased. No apparent difference in cholesterol efflux was observed between the proline containing formulations and the 7.5% sucrose formulation ( Figure 4C ).
  • turbidity is used to describe the cloudiness or haze in a solution. Strictly, turbidity arises from the multiple scattering events of visible light by elements present in the solution. Since turbidity arises from the net scattered light, it depends on the sample path length, protein concentration and size of the protein/aggregates/particles. Given that all reduced sucrose formulations contained the same protein concentration upon reconstitution and were measured with the same path length, differences in turbidity can be attributed to differences in the size and/or number of protein/aggregates/particles resulting from the various sucrose formulations.
  • Turbidity was determined with a LED nephelometer (Hach 2100AN Turbiditimeter, Loveland, CO.) using formacin as a standard. Results are given as relative light scattering (NTU).
  • Formulations containing 4-10% w/w sucrose produced similar turbid solutions upon reconstitution ( Figures 5A & 5B ).
  • Sucrose concentrations of less than 4% showed increased turbidity ( Figures 5E and 5G ). Based on turbidity, sucrose concentrations of 4% (w/w) and above are optimum.
  • lyophilized rHDL formulations prepared as per Example 1 was examined before and after storage (protected from light) at 40 °C for 12 weeks. Parameters tested included pH, turbidity, LCAT activation, HPLC-SEC (aggregate content, % lipoprotein in single peak and its relative retention time) and cholesterol efflux (C-efflux) (Tables 1 & 2). The results indicate that the formulations remain stable over the storage period.
